3 Claims. (Cl. 57-108) This invention relates to an improved mounting for separator sections in a spinning frame.

In spinning frames it is customary to have separators in the form of suitable plates disposed between the spindles and these separator plates are mounted on oscillatable bars, each bar having a plurality of separator plates mounted thereon, and the purpose of these separator plates is to prevent the ballooning of the yarns being spun on adjacent spindles from entangling one with the other. As is well known in the art, the spindles are usually mounted on a stationary spindle or bolster rail, and a ring rail is mounted for vertical up and down movement relative to the spindles so as to deposit the yarn on the bobbins located on the spindles in any desired manner.

While the spindle rail is in its lowermost position there is a substantial distance between the last pigtail through which the yarns pass and the traveler through which the yarns pass as they are being spun and twisted and wound onto the bobbins on the spindles. Much more ballooning is effected while the ring rail is in a lowered position than when it is in a raised position adjacent the top limit of travel of the ring rail, and it is necessary to have separator plates disposed between the spindles to prevent one ballooning yarn from entangling with an adjacent ballooning yarn, especially when the ring rail is in its lowermost position.

This invention relates specifically to suitable brackets in which the bars holding the separators are mounted so as to permit easy oscillation of the separators from operative position in which the separators are disposed between the spindles to inoperative position when the separators are moved backwardly from between the spindles so as to be out of the way during a dofling or donning operation. Heretofore, various means have been provided for supporting these bars on which the separators are mounted for oscillation usually up to or above ninety degrees so as to allow them to be quickly swung in units to inoperative or operative position. Each bar has a plurality of separators mounted thereon, a complete spinning frame of say thirty feet in length usually has from three to six bars extending from one end of the spinning frame to the other so that a plurality of the separators can be moved from operative to inoperative position or vice versa at a time without each individual separator having'to be moved.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- Figure 1 is a front elevation of a portion of a spinning frame and showing the invention applied thereto;

Figure 2 is a rear elevation of the structure shown in Figure 1;

Figure 3 is a vertical sectional view taken substantially along the line 3-3 in Figure 1;

Figure 4 is a view similar to Figure 3 but showing the separators moved to inoperative position;

Figure 5 is an elevation of one of the separator bar brackets in distended position before the same is stamped into final form;

Figure 6 is an isometric view of one of the brackets after it has been stamped from the blank shown in Figure 5;

Figure 7 is a view of one of the brackets and a separator and a portion of the separator bar showing the same removed from the ring rail looking from the outside of the spinning frame;

Figure 8 is a view similar to Figure 7 but with the bracket and separator removed from the same;

Figure 9 is an isometric view showing the reverse of that shown in Figure 7.

Referring more specifically to the drawings, the numeral 10 indicates a spindle or bolster rail having bolsters 11 mounted thereon in each of which a spindle 12 is mounted for rotation, each spindle having a whorl 14 integral therewith which is adapted to receive a belt for driving the same in a conventional manner. A conventional spinning frame is equipped with a ring rail 15 having a plurality of spaced spinning rings 16 mounted therein, each spinning ring having a flanged portion 17 on which a traveler 18 is mounted for movement. A spinning frame is also provided with a thread board 20 having pigtails 21 through which strands 22 are passed on their way from suitable yarn packages disposed in the spinning frame to the traveler 18 and from whence they are wound onto suitable bobbins 23 disposed on the spindles 12.

A ring rail is usually provided with down-turned front flanges 25 and a rear down-turned flange 26. A spinning frame is usually provided with a plurality of separators 30 which are secured to a separator holding bar 31 which is usually rectangular in cross-section. The invention relates specifically to suitable brackets for holding the separator bar 31 in position for oscillation from operative toinoperative position and vice versa.

The separator bar 31 has mounted thereon aplurality of stampedangle members 32 and 33 having suitable holes 34 therethrough for the passage of rivet 35 which pass through the separators 30 for holding them in position. These angle clips 32 and 33 have integral therewith lateral flanges 37 and 38 which have right angle bent portions 40 and 41 for fitting over the top of the separator bar 31 and may, if desired, have outwardly punched portions 36 for preventing rotation of a nut 39 which is disposed in cut-out portions C in the brackets 32 and 33.

The separator bar 31 has suitable holes therethrough through which a screw S may be inserted into the nut 39 to hold the brackets 32 and 33 in fixedly secured rela tion to the separator bar 31. Now, in order to suitably mount the separator bar 31 with its separators 30 for quick and easy movement from operative to inoperative position and vice versa, there is provided a plurality of sheet metal brackets 45 provided with an intermediate portion '46 having an elongated opening 47 therein through which the bolt 65 is passed and these sheet metal members are provided with upwardly projecting enlarged ears which have stamped therein a pair of openings 50 and 51 provided with triangular projections forming shoulders 53, 54, 55 and 56. The proximal ends of adjacent triangular projections are spaced from each other and divide each of the openings 50 and 51 into a pair of intercommunicating segmental-triangular openings.

After the blank 45 has been stamped and cut as above described, it is then bent along lines 57 and 58 to the position shown in Figures 6, 7 and 8 thus providing reinforcing ribs 60 and 61 and the openings 50 and 51 will be in the same horizantal plane. After a plurality of these brackets 45 have been secured to the rear flange 26 of the ring rail 15 by any suitable means such as screws 65 passing through the elongated opening 47 and being threadably secured in the flange 26 and vertically adjusted to where all of the brackets 45 will be in the of the separator bar 31 but allows oscillation of the separator bar in these brackets 45- when one of the separators 30 is engaged by the hand of an operator to oscillate the separators 30 and the separator bar 31 from the position shown in Figure 3 to the position shown in Figure 4 or vice versa.

It is noted that when the separators are in operative position between the spindles the separator bar will be engaging the shoulders53 and 54 and when the separator bars are moved to the position shown in Figure 4, the separator bar 31 will be engaging the shoulders 55 and 56. Now, it is also noted that the angularity of the shoulders 55 and 56 is such as to allow the swinging of the separators slightly more'than ninety degrees to thus insure their retaining their position as shown in Figure 4. Now, the distance between the top edge of the shoulder 53 andthe lower edge of the shoulder 54 is somewhat less than the distance between the outermost end of shoulder 55 and the outermost end of shoulder 56 so that when the separator bar is raised to the position shown in Figures 3 and 9, there will be a slight binding eifect or a rather tight fit to cause the separators and the bar 31 to remain in vertical or adjusted position as shown in Figure 3 and not tend to move to the position shown in Figure 4 due to the vibrations of the machine.

By having the openings 50 and 51 entirely enclosed it prevents accidental removal of the separator bars from their brackets and also by having the brackets 45 made from a stamping of sheetmetal they are much more easily and less expensively manufactured than other attempts heretofore wherein die-cast brackets have been employed for accomplishing the supporting of the separator bars and their associated separators.

In the drawings and specification there has been set forth a preferred embodiment of the invention and, although specific terms are employed, they are used in a generic and'descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
